Flood Early Warning Detection System Prototype Based on IoT Network

This paper proposes a basic prototype of flood early warning detection system based on internet of things network. This paper will also explain regarding how the system works (using Arduino and ultrasonic sensor), where the data should be sent (to the cloud server), and who can access the system to get the information about the current water level (involves GSM and GPRS module). The system will give the flood early warning when the water level reaches certain height. The results show that the system was running well, but there are still some drawbacks: less sensitivity of sensor readings (about 20% accuracy) and low responsiveness of GSM and GPRS modules to some commands that effects the Arduino functionality. However, based on our experimental results, this system will be useful as one of solutions in order to reduce the number of flood casualties that might happen in the future.
